Answer:
Edge = 12
Total Surface Area = 72
Step-by-step explanation:
Volume of the cube = 1728
Length of the edge = ![\sqrt[3]{1728} = 12](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7B1728%7D%20%20%3D%2012)
We know that
TSA (Total Surface Area) = 
where a = length of edge of cube
So,
TSA of cube = 
Remember
(a/b)/(c/d)=(a/b)(d/c)=(ad)/(bc)
convert to improper fractions
8 and 1/2=8+1/2=16/2+1/2=17/2
2 and 1/4=2+1/4=8/4+1/4=9/4
8 and 1/2 divided by 2 and 1/4=
(17/2)/(9/4)=
(17/2)(4/9)=
(17*4)/(2*9)=
68/18=
34/9=
27/9+7/9=
3+7/9=
3 and 7/9
